WASHINGTON, Sunday, May 21.

The military display of the present week is the absorbing topic of excitement and anticipation among all classes. The turnout of spectators promises to be immense, greater than on any previous occasion for many months. Gen. MEADE issued an order to-day prescribing the movements of the Army of the Potomac on the day of their parade, and previously, with reference to getting into position. The cavalry corps, under Maj.-Gen. MERRITT, will lead the column, followed by the Ninth Corps, and Gen. DWIGHT's division of the Nineteenth Corps. The Fifth Corps will follow, and the Second Corps bring up the rear. The artillery will be stationed in their appropriate places, and where practicable will move battery front. The regiments will be formed in column of companies, each company to consist of twenty files, or twenty men abreast. The cadence step will be observed all through the avenue until reaching Seventeenth-street. It is estimated that at this rate eight thousand men per hour can pass the reviewing officer.

It has been decided by the government that after the grand review, every regiment to be discharged will be allowed to go to the State and district in which it was raised, carrying its arms and colors with it, and be there mustered out. This is eminently just, and will be highly gratifying to the great body of our soldiers and to their friends.

The city is as full as it was at the inauguration, while still greater crowds are expected to-morrow and Tuesday morning. People are coming from all parts of the country, and many men of prominence will be here. Among the arrivals from New-York, I notice several prominent bankers, among whom are JOHN D. JONES, GEO. D. COE, J.D. VERMILYE and others.

As an evidence of the result of the order for mustering out all troops whose terms expire prior to Oct. 1, it may be stated that after this is done, the Fifth Army Corps alone will retain fourteen to fifteen thousand men.

Maj.-Gen. SHERMAN visited the city yesterday, the first time in several years, and spent considerable portion of the day at Gen. GRANT's headquarters, at the War Department, and subsequently had an interview with the President. Gen SHERMAN is said to have expressed himself as much pleased with his reception by the President.

There arrived here yesterday a delegation of North Carolina Union, men, consisting of Hon. W. HOLDEN, the well known conservative leader of that State, and Mr. W.R. RICHARDSON, editor of the Raleigh Progress, Hon. R.P. DICK, of Greensboro; W.S. MASON, J.P. H. RUSS, and JOHN G. WILLIAMS, of Raleigh. They come as representative of the radical union sentiment of the State, and the purpose of their mission is a full and free consultation as to the best and most speedy means of reorganizing the State government of North Carolina.

To this end have have already had one interview with the President, and will have another to-morrow.

These gentlemen assert that the party known during the war as the "Conservative" party in that State, was in reality composed mainly of Union men, who were compelled to assume the guise of opposition to the ultra advocates of secession, and that two years age Gov. VANCE was elected to his position as a professed representative of that party, but that he betrayed those who placed him in power by becoming the tool of JEFF. DAVIS. The first stop taken in North Carolina reconstruction will be the appointment of a Military Governor, under whose call a State Convention shall meet and devise measures for the proper amendment of the State Constitution and the election of State officers and members of Congress.

In addition to the gentlemen above named, Ex-Gov. DAVID L. SWAIN and Messrs. WM. EATON and L.F. MOOSE, of North Carolina, are in the city.

Gen. SHERIDAN's new command virtually supersedes Gen. CANBY in the command of the Military Division of the Mississippi. Gen. CANDY has been assigned to the command of the Department of the Gulf, which relieves Gen. BANKS, who is ordered to report to the Adjutant-General of the army. The Department of the Gulf is considerably extended and will hereafter include several States heretofore included in other departments. This action, so far as it refers to Gen. BANKS, is of a purely military character, and is not done as the result of the labors of any investigating committee, or because of charges preferred or pressure brought to bear against Gen. BANKS by the politicians now here. These parties have never had an interview with Gen. GRANT, and he knows nothing of their views of wishes. This change in these several commands has been contemplated several weeks.

The departure of Gens. SHERIDAN and GUSTER and MERRITT, with their respective staffs, for a new field of operations west of the Mississippi was made the occasion last night and to-day of quite an ovation by the forces lately under their command, and of many congratulatory leave-takings by brother officers and civilian friends. Late last night a splendid band, stationed under the window of Gen. GRANT's room at Willard's Hotel on Fourteenth-street, paid Gen. SHERIDAN the compliment of a fine serenade. At an interval in the music, the General was called upon for a speech, to which he responded very briefly and pithily as follows:

GENTLEMAN: I am very much obliged to you. My only regret is that I have been so long in the service that I can't make a speech. I am very much obliged to you. Good night.

With this shot the crowd took their departure.

This morning, about 9 o'clock, the cavalry corps moved from their camp, south of the Potomac, across Long Bridge, and marching up Fourteenth-street, passed in review before their old commander, who took a farewell look at his brave troopers, who never yet failed him on the battle-field, and whose services at Five Forks and Appomattox Court-house were of inestimable value to the republic. The troops moved by platoons, and presented, in reality, a veteran appearance. Maj.-Gen. MERRITT commanded the corps, Gen. CROOK being on leave of absence. Maj.Gen. CUSTER led his division in his usual dashing style.

After passing through the avenue they moved out east of the Capitol and went into bivouac, preparatory to the great parade of Tuesday, when they lead the column. As the corps passed through the streets to-day it attracted great attention and admiration from the torn and battle-scarred appearance of its guidons and flags, and the veteran aspect of the gallant men and officers.

At six o'clock this evening Gen. SHERIDAN and staff took their departure for the West via New-York and Cincinnati. The General is accompanied by the following members of his staff: Brevet Brig.-Gen- Forsyth, Chief of Staff; Lieut.-Col. Newall, Assistant Adjutant-General; Maj. Lee, Assistant Adjutant-General; Lieut.-Col. SHERMAN, Inspector-General; Col. FORSYTH, Maj. MOORE, Maj. PARSONS, Maj. KIP and Capt. SHERIDAN, Aids-de-Camp; Maj. GILLESPIE and Capt. ALLEN, Engineers; Capt. MCGONIGAL, Chief Quartermaster; Surgeon GHISELIN, Chief Medical Officer. Gen. SHERIDAN will take command of all the troops west of the Mississippi, headquarters in the field. Gens. CUSTER, and MERRITT will remain here until Wednesday to participate in the review.

Assistant Secretary of War DANA has announced his intention of resigning, to take effect in two months, for the purpose of assuming the editorial conduct of a now Republican daily paper to be started in Chicago.
